عنوان انگلیسی The Insulin-Producing Cells Generated from Rat Adipose Tissue Mesenchymal Stem Cells via Pdx1 Overexpression Activate an Immune Response both in Vitro and in Vivo
چکیده انگلیسی مقاله Background: The current work investigated the immunological features of insulin-producing cells (IPCs) generated from rat adipose-derived mesenchymal stem cells (ADSCs) both in vitro and in vivo. 
Methods: The research was carried out at Ahvaz Jundishapur University of Medical Sciences in 2023. ADSCs were derived from rat adipose tissues and differentiated into IPCs. The control group included undifferentiated ADSCs. The amount of secreted insulin was measured using ELISA. The expression of major histocompatibility complex-I (MHC-I) and MHC-II, cluster of differentiation 40 (CD40), and CD80 by IPCs in vitro was assessed using Western Blot analysis. The in vivo study was performed on 10 male diabetic rats. The experimental group received 107 IPCs in the peritoneal cavity. The control group received 107 undifferentiated ADSCs. After 4 hours, the expression of CD3a and CD45 by immune cells collected from the peritoneal cavity was measured using flow cytometry. All parameters were statistically analyzed using a t test.
Results: The differentiated cells secreted much higher amounts of insulin than the control group (P=0.04). IPCs exhibited higher expression of MHC-I and MHC-II, CD40, and CD80 (P=0.02, P=0.008, P=0.07, and P=0.02, respectively). The experimental group showed higher levels of CD3a and CD45 expression than the control group (P=0.07, P=0.04, respectively). 
Conclusion: Functional IPCs generated by ADSCs differentiation exhibited immunogenic activity both in vitro and in vivo. Immune-modulating strategies are required for the effective transplantation of the differentiated IPCs generated in our study.
